It accommodates thermal expansion and contraction of transformer oil, maintaining proper oil level and preventing pressure buildup in the main tank.
Carbon steel (e.g., Q235B) and stainless steel are typical. Material choice depends on corrosion requirements and environment.
Leak rate is tested using a helium mass spectrometer, with a specified maximum of 0.1 Pa·m³/s. Confirm the test method and acceptance criteria with the supplier.
Relevant standards include GB/T 6451 for oil-immersed transformers, GB/T 709 for steel plates, GB/T 700 for carbon steel, ISO 12944 for corrosion protection, and IEC 60529 for ingress protection. Verify compliance with the manufacturer.
